Claims.

This invention relates to an improvement in supporting and lockingdevices, and is particularily adapted to the Powers printinginterpreters disclosed in the patent application of William W.

5 Lassker, Serial Number 637,401, filed October 12,

In the machine disclosed in the above cited Lasker application, it isnecessary that the interpreter plates be put into or taken out of saidmachine one by one, to correct troubles such as a jammed card, thereplacement of a printing ribbon, etc. By incorporating the improvementsdisclosed in the present application with the machine disclosed in theabove cited Lasker application, the need for the above described tediousremoval or change of plates is obviated. Groups of plates may beassembled into single units for use in certain differing fields, such asalphabetic or numeric. A hinged frame is provided in this invention,which is adapted to carry the printing interpreter plates. With theincorporation of this frame, it becomes quite a simple matter to removejammed cards or replace a ribbon, merely requiring the lifting of saidframe on its hinge member.

Another feature of this invention is the provision of means whereby saidframe can be liftedat but one small part of a cycle of operation of saidprinting interpreting machine, at which part of said cycle all thesensing pins are. in their lower position, and no great damage would bedone to the mechanism, should said frame containing said plates, bedropped accidently.

Still another feature of this invention is that should said frame beraised and the drive mechanism moved, said frame will be automaticallyblocked against downward movement, and held at a point where the lowestextremities of the stops mounted on the printing interpreting plateswhich are in turn mounted in said rockable frame, will be clear of anyinterponents of the sensing mechanism which may be elevated.

One object of this invention is to provide a movable frame adapted tocarry a plurality of interpreter plates.

Another object of this invention is to provide an automatic lockingmechanism operable upon a movable frame in such a way as to prevent 50damage being done to the mechanism of a printing interpreting machine byaccidently dropping said frame.

Another object of this invention is to provide a device wherein groupsof interpreter plates can be fastened together as a single unit.

Other objects and structural details of the invention will be apparentfrom the following description when read in connection with theaccompanying drawings, wherein:

Fig. 1 is an isometric view of a printing interpreting machine showingthe plate carrying frame in a partially raised position and one of itsholding set screws in an exploded position.

Fig. 2 is an isometric view of a group of interpreter printing platesassembled as a single unit.

Fig. 3 is a fragmentary isometric view showing the means used to holdthe lower front ends of a group of interpreter printing plates.

Fig. 4 is a front View of Fig. 2.

Fig. 5 is a sectional view showing the movable frame and lockingmechanism.

Fig. 6 is a fragmentary sectional view showing the relations between thelatching pins and the interpreter plate stops.

Referring particularily to the drawings, the method of assembling agroup of interpreter plates is shown in Figs. 2, 3, and 4. References tothe'forward end of the mechanism in Figs. 2, 3, 5, and 6. are directedto the left side in all of said views. Because of the multiplicity andthicknesses of parts mounted to each plate, and the close relationshipof plates to each other, when placed in a printing interpreter, itbecomes quite a problem to assemble a group of plates as a single unit,particularly in the lower front region. To hold the lower front part ofa group of interpreter plates I in such a relation to each other as tobe adapted to fit into the plate grooves of a printing interpretermachine, said plates I are set in crenelations 2 in an angle member 3 insuch a way as to have said angle member 3 fit against the lower frontcorner of the stop retaining member 4 (Fig. 2). The crenelations inangle member 3 are wide enough to allow a slight amount of sidewisemovement of plates I. A multiplicity of hooked angle members 5 are thenset between plate I and member 4 and around the rivet 6 after which thedownwardly extending leg of member 5 is bent over to lock said hookedangel member 5 in position (Fig. 4). The length of angle member 3 isgoverned by the number of interpreter plates, which may be desired to beassembled as a unit. The other three holding and spacing devices i, usedfor assembling a group of interpreter plates l, are heavy crenelatedbars, which space and hold said group of plates in alignment. The twoupper spacing and holding devices I have hinged handles pivoted theretoto facilitate handling.

To facilitate the clearing of .a printing interpreter of a jammed card,the replacement of inkribbons, etc., this invention includes theincorporation of a rockable frame 8 (Fig. 5), pivotally supported by themain framework and adapted to hold a group of interpreter plates I, withthe printing interpreting machine disclosed in the above cited Laskerapplications.

During a cycle of a printing interpreter there are times when one ormore stops 9 (Fig. 6), may be elevated by the sensing mechanism and heldelevated by the action of theircorrespond'rngrlocking slides l8 uponcorresponding interponents I I. Now, it may be seen that with theincorporation of frame 8 in a printingrin'terpreter, it'wculd bepossible to rock said frame 8 when'the mechanism is in the above citedposition. To lift or rock frame 8 it is necessary that universal retractbar l2 (shown diagrammatically in Fig. 6), be removed thereby allowingall the measuring 'bars l3 to be drawn forwardly by their springs.Should frame 8 be :accidently' dropped when the mechanism is in theabove stated condition, (interponents I l elevated and measuring bars 13forward) serious damagewould'be doneto either the interpreting printingplatesor the sensing mechanism or both. To-safeguard against :suchdamage being done, a locking mechanism has been provided (Figs. 1 and5). This locking mechanism includes a stud M fixed to "frame 8 in such amanner as to be adapted to engage a slot [5 in a reciprocatory lockingplate I 6 mountedtoa side frame I! of the printing interpreter. In theprinting interpreting machine disclosed in the above Lasker application,a cameoperated springheld universal bail I8 is provided foractuating allof the bell cranks l'9 (FigSfZ andfi) to positively restore any stops 9which may not'have returned to normal position :after the universallocking slide bail 20 has been actuated. In this invention, universalbail I8 .isalso'adapted to be operable upon locking plate 46. The bail|81is actuated once duringeach :cycle of said printing interpretingmachine, shortly after the latch plates l 8 have been actuated by thebail '20, to release any interponents H which may have been latched up.As may be seen .in Fig. .5 the only time at which locking plate lBis'free to'be manually operated is when bail I8 is "actuated rearwardly.With locking plate l3 in its rearmost position, it will be seen thatstud I4, fixed to frame 8 is clear of obstructions and consequently saidframe 8 is free to be rocked. When theroller cams 2| (one not shown),are not actuating the levers22 (one not shown), which carry saiduniversal R8, the springs '23 (onenot shown), cause the levers 22 toresiliently hold said bail l8 in its forward position. When frame 8 mmposition forinormal operation of the cited Laskerimachine, and lookingplate It is pushed forwardly by bail l8, slot 15 will engage stud 14fixed on frame 8, to lock said frame 8 against beingmoved. If lockingplate l6 should'be actuated to locking position by movement of shaft24'whileframe 8 is raised and an attempt then made to lower said frame 8to operating position, the-stud M on said frame 8 will engage thesurface 25 of locking plate 58 and thereby block further downwardmovement of said frame 8 until said shaft 24 is turned to a point wherecams 2| enable the manual rearward movement of said locking-plate l6.

As shown in the above cited Lasker application, the levers 22 are singlearm levers operating only on bell-cranks l9. If this single-arm type oflever is used with the present frame 8 it is posplate l6.

sible to press the locking plate I6 rearwardly against the tension ofthe spring 23 to lift frame 8. To eliminate this possibility an arm 26carrying a roller 2'! has been added to one of the springheld levers 22(Fig. 5). Also, to the shaft 2 a notched disc 28 has been added in sucha position as to have its periphery engageable by said roller 2'1.During normal operations of the printing interpreting machine the roller'21 does not contact the periphery of said notched disc 28; however, ifan attempt be made to manually render the locking plate 16 ineffectiveat any but the proper time the roller 21, after a very short travel,will contact the periphery of notched disc 28 and thereby prevent themanual operation of locking A pair of locking screws 29 (Fig. 1, one notshown) are provided to hold frame 8 solidly during-operation of theprinting interpreter machine.

While there are above described but two embodiments of the invention, itis possible to produce still other embodiments without departure fromthe inventive concept above disclosed, and it is, therefore, desiredthat only such limitations shall be imposed on the appended claims asare states therein, or required by the prior art.
